Method for Controlling a Device

1. A method for controlling a device having a user interface by which functions of the device are controlled, comprising: dividing the functions into categories and the categories into subcategories; representing the categories by primary regions on the user interface, the primary regions arranged in a schema and physically containing elements which each represent a subcategory of a category of one of the primary regions; responding to a selection of an element by expanding only one primary region by displaying a secondary region, such that the one primary region is physically expanded by the secondary region, the secondary region being a region in which control elements are displayed for at least one function which is associated with an associated subcategory that is represented by the element selected, wherein an entire display area of the one primary region and all the elements contained in the primary region remain displayed when the one primary region is physically expanded by the secondary region and displaying the secondary region includes using an animation that pushes remaining primary regions from the user interface; and controlling the at least one function by way of the control elements.

2. The method as claimed in claim 1 , wherein the device is a mobile terminal device.

3. The method as claimed in claim 1 , wherein the device forwards control commands to another system.

4. The method as claimed in claim 3 , wherein the another system is a house automation system, wherein the categories are associated with rooms of a house, wherein the subcategories are associated with room properties, and wherein the functions regulate the room properties.

5. The method as claimed in claim 1 , wherein the primary regions are displayed as bars.

6. The method as claimed in claim 1 , wherein the elements are icons.

7. The method as claimed in claim 1 , wherein the elements that each represent a subcategory of a category of one of the primary regions are displayed within the respective primary region.

8. The method as claimed in claim 1 , wherein, when a primary region is expanded by a secondary region, the expanded primary region is expanded by the secondary region in correspondence with the schema.

9. The method as claimed in claim 1 , wherein, in addition to being physically expanded by the secondary region in response to selection of an element, the one primary region is physically expanded by the secondary region in response to selecting any portion of the one primary region.

10. The method as claimed in claim 9 , wherein, when the one primary region is physically expanded by the secondary region in response to selecting a portion of the one primary region that does not contain any of the elements, the secondary region displays control elements associated with an associated subcategory that is represented by a first element from among the elements contained in the one primary region.

11. A device having a user interface by which functions of the device are controlled, comprising: one or more processors configured to: divide the functions into categories and the categories into subcategories; represent the categories by primary regions on the user interface, the primary regions arranged in a schema and physically containing elements which each represent a subcategory of a category of one of the primary regions; respond to a selection of an element by expanding only one primary region by a secondary region, such that the one primary region is physically expanded by the secondary region, the secondary region being a region in which control elements are displayed for at least one function which is associated with an associated subcategory that is represented by the element selected, wherein an entire display area of the one primary region and all the elements contained in the primary region remain displayed when the one primary region is physically expanded by the secondary region and displaying the secondary region includes using an animation that pushes remaining primary regions from the user interface; and control the at least one function by way of the control elements.

12. The device as claimed in claim 11 , wherein the elements that each represent a subcategory of a category of one of the primary regions are displayed within the respective primary region.

13. The device as claimed in claim 11 , wherein, when a primary region is expanded by a secondary region, the expanded primary region is expanded by the secondary region in correspondence with the schema.
